The high-speed railway vibration effect on environment is more and more concerned in recent years. Technical measurements are needed to minimize the damage to the environment, which is caused by the new transportation vehicle. It has been improved that the open trench can be used for this purpose because of its easy construction and the relatively good isolation effects. The finite-element software ABAQUS is adopted to analyze the open trench isolation effects. In order to simulate the semi-infinite space of soil condition, the infinite element and visco-elastic boundary is used in this model. The parameter ARF is introduced in the calculation procedure. The reduction effect of different factors which influence resulting vibration reduction, such as the depth, the width, the location of the trench and the frequency of the vibration load are also discussed. The obtained approaches can be referred by the designer in this area.
